Do the greyscale active matrix screens in the PowerBook 1xx series consume significantly more power than the passive matrix displays? I know that the early colour LCDs would quickly drain a 1xx-series machine's battery, but I cannot find much to go on re. the greyscale ones, beyond the fact that Apple's spec sheets give the battery life of a 180 as the same as a 160. Well, they would say that….

If, however, the difference is indeed negligible, and given the ease with which a 1xx series machine can be re-celled, I think I'm going to begin looking for a PowerBook 180 (I notice a couple of nice examples on a certain auction site at the present moment, for instance).

My 160's passive matrix screen is awful, and though I have a nice PowerBook 150 on which the screen is surprisingly crisp, I like to have high end examples of Apple's old wares. For these purposes, the PowerBook 180 is king.
